3 Most Common Abrasive Blasting Methods

There are many benefits to using abrasive blasting machines to clean surfaces, such as the fact that they are very cheap and have been shown to be much more effective than other methods in terms of how quickly and thoroughly they clean.

As a result, the abrasive blasting industry like has grown to include several variations.

Each of these topics will be explored in detail in the following sections.

#1 Sand Blasting

At high speed, silica abrasive particles are shot from sandblasting machine onto the surface of a component.

High-speed propulsion propels the abrasive silica or quartz onto the surface being worked on. Because of its sharpness and uniformity in size, this abrasive gave a smooth, even finish.

Because of their fast speed, these particles will easily remove any impurities from the part’s surface. Sandblasting is a common method for eliminating rust from metal.

The dry abrasive particles are fired using the air pressure provided by the mechanism.

Hand-held nozzles are often used to discharge the abrasive sand and air mixture. There are environmental rules that dictate where sandblasting may be done since it is done more openly.

Health risks include Silicosis is caused by inhalation of toxic silica dust. No longer does abrasive blasting use this method because the abrasive could be ingested or leaked into the environment, which makes it dangerous.

Best for: Ideally suited to a wide range of surfaces requiring a high degree of adaptability,

#2 Wet Blasting

When it comes to air blasting, managing the quantity of dust that is released into the air is a major issue. Wet blasting was created to address this issue.

An air-powered abrasive is driven by this instrument, which has a water-injection nozzle at the end of the nozzle. A nozzle even lets water out in different ways after the abrasive has been mixed with water, so it can be used in different ways.

Regardless of which method is used, the nozzle releases a high-pressure stream of air, water, and abrasive particles that slam into the surface to clean it. Environmental standards require that the cleaning waste be confined and properly disposed of.

Best for: surfaces where airborne dust and other blasting byproducts need to be minimized.

#3 Vacuum Blasting

Dustless blasting is another name for vacuum blasting. A vacuum suction is used to remove any abrasives and surface impurities that are driven by the blasting machine. These elements, in turn, are pulled back into the control unit as soon as they are released.

Vacuum blasting has the advantage of more effectively recycling used abrasives, which may save money. In addition, the cleaning process produces less waste.

Vacuum blasting is slower than other procedures because of the recycling function.

Best for: This machine can be used for any abrasive blasting that needs the least amount of debris to be thrown into the air.
